Circling around the Milky Way are between 20 and 25 known satellite dwarf galaxies, which are smaller clumps of stars bound in orbit around the Milky Way by gravitational attraction. Some pessimists predicted the Milky Way was doomed to a grizzly death by dismemberment if enough of these galaxies collide with it. In fact, scientists think many satellite galaxies have already rammed into...
